摘要
以硅藻土基多孔陶瓷为载体,进行粘细菌的吸附固定实验.对不同处理多孔陶瓷的吸附量进行比较,并对吸附条件进行优化.研究表明,由2.0mol/L FeCl3处理的硅藻土基多孔陶瓷对粘细菌的吸附效果较好,最佳吸附条件为温度30℃,转速100r/min,吸附时间3.5h,吸附量达14.45mg/g.为多孔陶瓷固定粘细菌发酵制备埃博霉素提供实践基础.
Taking the diatomite-based porous ceramics as vector, the adsorption capability of porous ceramics to Myxobacteria was studied. Compared the adsorption a ramics of different treatment, and optimized the adsorption conditions. showed that the 2.0 mol/L FeCla and optimal conditions are followi adsorption time of 3.5 h,the adso could bring better adsorption efficiency ng ： temperature of 30 ℃, shaking speed rption capacity reached 14.45 mg/g. The mong porous ce- The test results of Myxobacteria, of 100 r/min and research provides practical basis for the fermentation of immobilized Myxobacteria.
